In reality as an unlicenced fitter it would be you performing the maintenance and a type rated licenced engineer (B1 or B2) with that aircraft type specific company approval who will oversign your work. He/she may or may not directly be involved in that task - dependant on your training and experience, both basic & type.
Should you join a firm with limited experience of a given aircraft
type, expect sound guidance and preferably a B1 or B2 who will
teach you not only what you need for that task but WHY you
are performing it.
There is a high standard of work and integrity expected from any
fitter, technician or Licenced Aircraft Engineer. Apart from my formal
preamble, I still find the work fun and it is in comparison with others,
an enjoyable, rewarding career.
